noise jitter effects
can ground loops over usb induce jitter — Preceding unsigned comment added by 77.35.48.216 (talk) 03:31, 23 March 2013 (UTC)
 * If you mean monitor jitter, I guess it's not inconceivable, but it seems very unlikely. (Presuming you have a CRT monitor. If it's LCD, no chance at all.) Looie496 (talk) 05:06, 23 March 2013 (UTC)

 * The VideoLan guys (who make VLC) have a very explicit mechanism for reporting bugs. They are crotchety folks, because they have received spammy, misspelled, and uncapitalized reports for many years; if you expect them to volunteer time, spend some time reading how to report a bug.

Chrome
Every time I fire up Google Chrome, a few webpages like http://websearch.just-browse.info/ and (for some weird unknown reason) not one, but two tabs of google.com open up by default. I want a way to switch off the default sites that chrome accesses when I run it. Can anyone tell me exactly where to go and tweak what so I can see the startup sites and turn them off? (Much like turning off unneccessary start-up programs when switching on your computer) 14.96.97.124 (talk) 15:58, 23 March 2013 (UTC)

You could tyep in the address bar: “chrome://settings/” and there, in the “on startup” section select the “Continue where I left off” option  — Preceding unsigned comment added by Iskander HFC (talk • contribs) 19:50, 23 March 2013 (UTC)

All that stuff without the quotesIskánder Vigoa Pérez (talk) 19:52, 23 March 2013 (UTC)
 * Thanks. That totally worked. Except now when I start it, the new tab page opens, although it's set to "open a set of pages" and the set of pages contains only google.com's address (google's my homepage). Any way to fix this little bug? Everything else is fine otherwise. 14.99.179.58 (talk) 20:49, 23 March 2013 (UTC)

RPC-1 firmware or RPC-2 firmware?
How in general can one determine whether one has RPC-1 firmware or RPC-2 firmware?

I am specifically curious about a Mac G4 Powerbook from 2005 and a Gateway NV78 Laptop from 2009. Thanks. μηδείς (talk) 20:28, 23 March 2013 (UTC)
 * This site has a nice bit of information, and suggests using driveinfo to determine your drive's firmware. I can't vouch for the program's ability, nor do I know whether it works on a Mac. - Cucumber Mike (talk) 21:01, 23 March 2013 (UTC)
 * I think all drives manufactured starting in 2000 are RPC-2 unless you reflash them (see e.g. ). If you're interested in reflashing, note that free-software players like VLC will play discs from any region even on an RPC-2 drive, and commercial players will enforce a region even on RPC-1 drives by some software mechanism that may be difficult to circumvent. -- BenRG (talk) 23:27, 23 March 2013 (UTC)
